To all whom it may concern:

Be it known that 1, CHARLES W. HUN TER, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful In'iprovements in Clamping Devices, of which the following is a specification.

Prior clamping devices for gluing up of wood work, for pianos and other cabinet articles, have employed large raddles on the cross rods of which have been mounted individual clamps, and individual frames have been used having several clamps swinging and sliding on rods at several s ideso'f such frames, but no such prior frames have been made that were adjustable in size additional to the changes of their clamps; nor has there been a frame adjustable as to its own size and having clamps mounted therewith and adjustable in similar dimension to that of the frame and in addition to the clamping motion of such clamps; all of which are now accomplished in the invention herein set forth. While a raddle is aconvenient form of carrier, any other suitable form of traveling means may be employed with the present invention.

In the drawings Figure 1 is a side view of a raddle form clamping machine for cabinet gluing; and Fig. 2 is a plan view of the leftpart of Fig. 1 showing the details of one of the adjustable frames and the clamps therewith.

Shafts l and 2 at each end of the raddle 3 are employed to carry the raddle and by the intermittent revolution of said shafts l and 2 progress the raddle 3 step by step to allow the successive access to each of the frames 4: for the placing of the wooden parts thereon that are to be held by the clamps 5 and 6 which are carried with each frame at. These frames l are preferably so mounted on the rods 1 fixed with the side bars of the raddle 3 that each frame 4 will in turn lie horizontally out from the raddle 3 when at the end of the raddle so that each such frame at at such time will be in convenient position for the workman to place and clamp those Wooden parts thereon that are the next to be glued and clamped. After the gluing and clamping of the wooden parts placed with frame 4-. then so extended horizontally at the end of the raddle 3, the

neXt movement of the shafts and raddle carry that frame away from the end position, and another frame is by the same movement of the raddle brought into position for the next gluing and clamping job.

The clamps 5 act in a direction outwardly or *ra dially from the raddle, while the clamps 6 act transversely of the raddle and its direction of travel. Each frame at is adjustable in one or the other, orbothof its main dimensions, the present showing being in the same direction as the width of the raddle and the machine, that is, crosswise of the direction of travel of the raddle 3. This enables a quick adjustment to variations of size of work greater than can be easily cared for by the screw clamping action of the clamps (5 and without the slowness of such extensive screw adjustment, each clamp 6 may have additional means besides its clamping action for setting it to large variations in size of the work to be clamped by it, as by the sliding joint 7 and bolt 8 or any other suitable means, also enabling each clamp (3 to be altered to suit any adjusted change of width of its frame 4. Lugs 9 and 10 serve to hold the work at the edges opposite the clamp screws 5 and 6. The change in width of the frame 4 may be by means of bolts 11 fitting to the several holes 12 in the two relatively slidable parts 13 and 14 of the frame l.

lVhat I claim as my invention is 1. A multiple clamping machine having a traveling means and a plurality of clamping frames mounted on said traveling means in successive positions in direction of the travel of said traveling means, each said frame adjustable as to an integral dimension in direction transverse of the said traveling means and the direction of travel of said traveling means, and a clamp means on each frame clamping in the same said direction as the said adjustment of that frame, and having a main member supplemental to the said frame and also additionally adjustable in the same said direction as before stated.

A multiple clamping machine having a traveling means and a plurality of clamping frames mounted on said traveling means in successive positions in direction of the travel of said traveling means, each said frame integrally adjustable in a main dimension thereof, and each said frame having a plurality of clamping means combined therewith and carried thereby.

3. A multiple clamping machine having a traveling means and a plurality of clamping frames mounted on said traveling means in successive positions in direction of the travel of said traveling means, each said Copies of this patent may be obtained for five cents each,

sion in direction transverse of the said traveling means and the direction of travel of said traveling means. Y

5. A multiple clamping machine havin a traveling means and a plurality of qua rangular clamping frames mounted on said traveling means in successive positions in direction of the travel of said traveling means, each said frame adjustable as to an integral dimension.

6. A multiple clamping machine having a traveling means and a plurality of clamping frames mounted on said traveling means in successive positions in direction of the travel of said travelingineans, each said frame adjustable as to an integral dimension.

It is hereby certified that in Letters Patent No. 1,285,569, granted November 19, 1918, upon the application of Charles W. Hunter, of Cincinnati, Ohio, for an improvement in Clamping Devices, an error appears in the printed specification requiring correction as follows: Page 1, line 75, strike out the Words may have and insert the word having, and that the said Letters Patent should be read With this correction therein that the same may conform to the record of the case in the Patent Ofiice.
